Sodium perborate (PBS) is a white, odorless, water-soluble chemical compound with the chemical composition NaBO3. It crystallizes as the monohydrate, NaBO3·H2O, trihydrate, NaBO3·3H2O and tetrahydrate, NaBO3·4H2O. The monohydrate and tetrahydrate are the commercially important forms. The elementary structural unit of sodium perborates is a dimer anion B2O4(OH)42–, in which two boron atoms are joined by two peroxo bridges in a chair-shaped 6-membered ring, and the simplistic NaBO3·nH2O-type formulas are just a convenient way to express the average chemical composition.

Famous quotes containing the word sodium:
“Every reader of the Dreiser novels must cherish astounding specimens—of awkward, platitudinous marginalia, of whole scenes spoiled by bad writing, of phrases as brackish as so many lumps of sodium hyposulphite.”
